title: [Regularities of structural and functional visual system changes in patients with myopic refraction and presbyopia].
abstract: Two age groups of 57 patients with noncomplicated low or moderate myopia were examined to reveal the regularities of structural and functional visual system changes in patients with myopic refraction and presbyopia. Characteristics of visual impression, anatomic and physiologic parameters were studied. Presbyopia development in patients with myopic refraction was found to occur on the background of significant changes in anatomic proportions and optic parameters of the eye, decrease of functional capability of visual system and development of abnormal functional system of visual perception. The key mechanisms of presbyopia development in myopia besides the accommodation decrease are pupil dysfunction and binocular interactions disintegration i. e. all the near vision reflex components.
